To all whom, it mag concern.-

Be it that I, FREDERICK A. WUEsT,

. a citizen of'the United States, residing at;

Lawrenceburg, in the county of Dearloorn and State of Indiana, haveinvented certain new and useful Improvements in Saw-Sets;

and I do declare the fol-lowing .to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

. My invention relates to im rovements. in

simple and eflicient hand-tool by means orwhich the teeth of a saw willbe quickly and accurately set.

' Another object of the invention is to provide a saw-setting tool whichmay be adapted for use on saws of various sizes.

Another object of the invention isto provide a simple, convenient, andefficient de- 1 vice o1 this character in which the depth and angle ofthe-set may be varied as desired.

A further .object :of the invention is to improve and simplify theconstruction and operation'of devices of this character, and therebyrender the same more durable and eflicient in use and less expensive tomanufacture. I

The above and other objects, which will appear as the nature of myinvention is better understood, .are accomplished by means of theconstruction illustrated in the accompanying drawings, in which I Figure1 is a perspective view showing the manner in which my improvedsaw-setting tool is used. Fig. 2 is a perspective viewof the under sideof the tool, the saw being removed. Fig. 3 is a vertical sectional view.Fig. 4 is a detail transverse sectional view taken on the planeindicated by the line 4 4,

in Fig. 3. Fig. 5 isa perspective view of the anvil, and Fig. 6 is asimilar view of the saw guide and clamp. Q

Referring to the drawings by numeral, 1 denotes my improved saw-setwhich is of the swinging-hammer type and in the form of ahand-tool'which may be readily used upon saws of any description whenclamped in a vise or otherwise firmly held. .The device or toolcomprises an anvil 2, ahandle 3, a saw clamp and guide 4, and'a swinginghammer 5. The anvil 2 is in the form of a metal block, which has formedintegral thereon or rigidly secured thereto by being secured in a recess6 by means of a screw 7 an arm 8, to the [1 per or outer curved end ofwhich is pivota connected the hammer5. The anvil; 2 has the recess 6 inone of its side faces, and its opposite side face is a cavity in whichthe;

head of the screw 7 is countersunk. The outer end face of the anvil iscut away to form a transverse shoulder '9, and the upper portion of saidend is formed with a die-face 10. The latter consists of twoangularlyi'disposed surfaces 11 12,"the larger and lowermost one ofwhich, 11, is adapted to bear 3 against the saw-blade adjacent to itstoothed #edge, and against the smaller and uppermost face 12 the teethare adapted to be'bent while being set by the hammer 5. The saw-blade isadapted to be held against the portion 1-1 of the die-face and in theproper position by means-of the combined guide and clamp 4, which ishere shown as being formed from a single piece of metal by shaping andbending the same to form a three-sided casing 13,

which surrounds the inner end of .the anvil,

and two guiding andclamping jaws '14, which project in oppositedirections from the ends of the casing 13 and which are in longitudinalalinement with each other and the die-(taco. 10 of the anvil, .so as toreceive the toothed edge of the saw-blade within them, as shown.

. The guiding andclamping jaws l4-are of-sub- -'star-itially U form, andinoneor both of them I may provide a set-screw '15, which is adapt.- edto govern the pitch of the setof the teeth, 'as presently ex lained.

The combined guide and clamp 4 is adjust.-

ably secured upon the anvil, so that the clamping and guiding jaws 14;may be adjusted vertically with respect to the .die-facelO-so as topermit the' use of the tool upon saws having teeth of different sizes.'ment the height or depth of that portion of the, tooth which is bent orset may be varied as desired. This adjustment is eiiected, as shown, byproviding a bolt 16 and using the handle 3 as a clamping nut or devicefor rig- By this ad-juste I idly clamping the combined guide and clamp 4in an adjusted position upon the anvi This bolt 16 passes through anopenin' formed in the lower portion of the anvil an has a portion of itsedge cut away or flattened to engage the shoulder 9 on the outer end ofthe anvil, and thereby prevent the bolt from turning when the handle orclamping device 3 is beingturned thereon. Said bolt also passes througha slot or elongated opening 17 formed in the portion 13 of the combinedclamp and guide 4, which portion is disposed between the rear or innerend of the anvil and the ferrule 18 of the handle. The screwthreaded end19 of the bolt 16 extends through an opening or bore formed in saidhandle and is engaged with a nut 20, fixed in a tubular socket orenlarged portion 21 of the bore in said handle. The nut 20 is placed inposition in the socket 21 through the open outer end of the latter,which after said nut has been secured against rotation is adapted to beclosed by a plu 22, as shown. It will be seen that the han le 3 is thusadapted to serve as a clamping-nut which when tightened upon the boltwill clamp the combined guide and clamp 4 firmly in an adjusted positionupon the anvil and which when loosened will permit the device 4 to beadjusted vertically upon the anvil, owing to the provision of the slots17, through which the bolt passes.

The hammer 5 consists of a handle 23 and a head 24. The handle 28 hasits upper end pivoted, by means of a threaded bolt 25, upon the upperend of the arm 8. The hammerhead 5, as shown, consists of a plurality ofstriking-faces 26 and is adjustably secured upon the free end of thehandle or lever 23, so that. any one of said striking-faces may bebrought into an operative position with respect to the die-face on theanvil. As shown, this head 24 is in the form of a strip of metal, whichhas its ends twisted, as shown at 27, to form two striking-faces 26 atits ends. These faces are of different widths, so that the tool will beadapted for use up on saws having teeth of different sizes or widths.The head 24 is adjustably secured upon the handle 23 by forming thelatter with a reduced flattened end 29, which is adapted to pass througha substantially rectangular-shaped opening 30, formed in said head, andwhich is screw-threaded to receive a clamping-nut 31.

The operation and advantages of the device will be readily seen uponreference to Fig. 1 of the drawings. It will be noted that by insertingthe saw-blade between the dieface of the anvil and the set-screws 15 inthe guiding and clamping aws 14, and pressing upwardly upon the handle3, which is preferably grasped in the left hand, the saw-blade will beheld firmly upon the anvil, so that when the hammer is swung downwardlyby the right hand, so as to cause one of its striking ends to bend oneof the saw-teeth, said tooth will be bent over upon the upper portion 12of said die-face. It will be seen that by adjusting the set-screws 15the angle or pitch of the set given to the saw-teeth may be varied asdesired and that by adjusting the combined guide and clamp 4 verticallyupon the anvil the length or depth of the bent portion of the teeth maybe varied as desired. By adjusting the head 24 upon the handle 23 of thehammer either its broad or narrow strikingface 26 may be brought into anoperative position, according to the size and width of the saw-teeth tobe set.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

The herein-described saw-set comprising the anvil-block having theshoulder on one side provided with the angularly-disposed faces 11, 12,the arm 8 having its inner end secured to the anvil-block, the guideforming the three-sided casing in which the anvil-block is placed, andhaving the guide-arms 14 extending from opposite sides of theanvil-shoulders, the set-screws carried by the said arms, the handlehaving one end opposed to the rear side of the anvil-block, said handleand guide being secured to the anvil-block and said handle being atsubstantially right angles to the arm 8, and the hammer having itshandle pivoted to theouter end of said arm, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FREDERICK A. WUEST.
